Supporting VUNI in DRNI Maarten Vissers 2011 -11 -10 v 01: added multiple virtual UNI with hairpin 1

Introduction The following slides analyse the ENNI DRNI within a Virtual UNI (V-UNI) scenario. The ENNI with V-UNI application is defined in MEF 28, and relevant text from MEF 28 is copied in slide 3. An ENNI with V-UNI example scenario is presented in slides 4 and 5, illustrating its data plane model with 802. 1 Q components. The example includes a Network Operator network deploying PBN and a VUNI Operator network deploying either PBN (slide 4) or PBBN (slide 5). A ENNI with V-UNI application deploys the RCSI specified in 802. 1 Qbc. This service interface also supports non V-UNI ENNI applications. An example is presented in slide 6, The data plane model of an ENNI DRNI with V-UNI example is presented in slide 7. The ENNI DRNI contains 2 x 2 nodes with 2 ENNI links. The associated layer stacks are presented in slide 8. Slides 7 and 8 identify the scope of the DRNI to be the S-VLAN Components attached to the E-NNI links. This scope is not aligned with the DRNI scope in axbq-haddock-multiple-drni-support-1011 v 01. pdf. 2

Virtual UNI Text from MEF 28, clause 3 “Scope and Key Concepts” R-UNI aware of very basic service attributes, not aware of service details, e. g. # EVCs. R-UNI maps all (C-Tagged, Prio-C-Tagged, Untagged) service frames to single OVC end point supporting UTA. Single BW profile & Co. S Network Operator provides Port-based Service at RUNI ENNI: an S-VID is used to map ENNI frames to the OVC end point supporting UTA. Single BW profile & Co. S Network Operator provides S-Tagged Service at ENNI 3

This implies that the DRNI is between the S-VLAN Components connected to the ENNI links. It also implies that there are Virtual V-UNI-N ports, consisting of two V-UNI-N ports as illustrated. Compare the Virtual V-UNI-N port with the Virtual CBP Port in an IB-BEB; functionality is the same. S CNP xx.
